SPECIFICATION forming part of Letters Patent No. 777,169, dated December 13, 1904.

Application filed September Z, 1903. Serial No. 171,584. (No model.)

To all whom, t may concern:

Be it known that I, OsoAn WooDwAnD, a citizen of the United States, and a resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in lype-Vriting Machines, of which the following is a specification.

My invention relates to type-cleaning dcvices for type-writing machines; and the object of said invention is to provide a simple, cheap, and efficient device of the character specified and one which can be readily attached to or detached from a type-writing machine.

To the above and other ends, which will hereinafter appear, my invention consists of the features of construction, arrangements of parts, and combinations of devices to be hereinafter described, and particularly pointed out in the appended claims.

In the drawings, wherein like reference characters indicate corresponding parts-in the various views, Figure 1 is a fragmentary perspective View of a sufficient number of parts of one character of type-writing machines to illustrate my invention in its application thereto. Fig. 2 is a front-to-rear vertical sectional View of the same with parts broken away. Fig. 3 is a detail central vertical sectional view of the type-cleaning device, the section being taken on the linea,I .fr of Fig. 2 and lool;- ing in the direction of the arrow in said ligure. Fig. 4L is a detail side view of one of the brush-heads. i

I have shown my device applied to a No. 6 Remington machine, and sufficient of such machine is shown to illustrate my invention in the application thereto.

The frame of a type-writing machine comprising the corncr-posts 1 and top plate 2 has mounted therein by hangers 3 a circular series of type-bars 11, which are connected by links 5 to the usual key-levers. (Not shown.) Extending upwardly from the top plate 2 are risers 6, which support one of the traverserods 7, upon which the carriage 8 is supported and guided in its movement from end to end of the machine. The top plate of the machine is apertured at 9 for the passage of the ribbon 1() across the type-well 11 of the ma chine. This ribbon is guided in its movement by a guide-plate 12, pivotod at one end at 13, so that the free end thereof may swing upwardly to its position shown in Fig. 1. A shift-rail it constitutes a bearing for the carriage, at the front side thereof, and is elfect ive to shift the platen and its :frame for upper and lower case writing. Connected to the shift-rail 24 isa block 15, which extends downwardly and forwardly from the shift-rail and is provided at its forwardly-projecting portion with a pointer 16, that cooperates with the indices upon the carriage-scale 17. The features thus far described constitute portions of the well-known N o. 6 Remington machine, and a further description thereof is unnecessary.

Thc frame 18 of the type-cleaning device is bent at 19, so as to form a groove in the for ward end thereof, that is adapted to receive the shift-rail 141C of a type-writing machine. This grooved portion is apertured at 20 in order to receive the depending block 15 on the shift-rail, so as to enter the same and prevent a longitudinal movement of the frame 18 on the shift-rail, as will hereinafter more clearly appear. The frame 18 is bent upwardly to form parallel side supports 21, which have openings therein constituting bearings for the horizontal shaft 22, said shaft being' loosely` disposed for rotation and having a limited longitudinal movement in said bearings by reason of which in the ordinary operation of the device the brush will be constantly shifted widthwise to bring different portions of its surface in contact with the type. A rotary vertically-disposed brush 23 is provided with heads 24, that may be secured to the brush by rivets or screws 26 or by any other suitable means, and these heads are apertured near the centers thereof, as indicated at 27. The shaft 22 extends through cent-ral openings in the brush-heads, and pins or screws 28 are received in suitable openings in the shaft on cach side of the brush. The heads of these pins or screws extend laterally from the shaftand are of such dimensions and are so disposed that a portion of the head of each screw 28 is seated in the aperture 27 in the associated brush head, so as to cause the brush to rotate with the shaft and to prevent a longitudinal movement of the brush on the shaft. 1t will be seen that by removing' the screws 23 the shaft 22 may be longitudinally withdrawn from its bearings in the side plates 21 and from the brush, so that a new brush may be readily substituted for an old one when desired. The frame 13 is provided with an opening 29, through which the brush projects, as indicated in Figs. 2 and 3. The rear end of the frame has suitably secured thereto, as by screws 30, a spring-plate 31, which extends rearwardly and upwardly from its point of connection to the frame and is bent at 32 to form a groove by means of which the spring may be seated on and secured to a rod 33 on the carriage 8. The pressure of the spring'- plate 31 is sufHcient to clamp the device between the shift-rail 14 and carriage-rod 33 and to maintain the frame and brush over the type-well of the machine when the carriage is thrown back, as indicated in Fig. 1, at the same time permitting the ready disengagement and removal of the type-cleaning device. The spring 31 is provided with the indentation m, so that its function will not be interfered with.

The shaft 22 has a crank-arm 34, which carries a handle 35 and by means of which the shaft and brush may be rotated and given the fwslig'ht axial movement.

In using' the type-cleaning device the carriage is first thrown back to the position illustrated in Fig. 1, and the ribbon-g'uide 12 is swung to the position therein shown, when the ribbon is thrown to one side, so as to fully expose the type-well. The type-cleaning device may then be secured in position by first `placing the device fore and aft of the machine and centrallybf the type well, with the grooved portion 32 of the clamping-spring against the carriage-bar 33 and exerting a rearwardly and downwardly directed pressure against the spring until the grooved portion 19 of the frame receives the shift-rail 14 and the block 15 is seated within the opening' or aperture 2O in the frame. It will therefore be understood that the pressure exerted by the spring' is sufficient to holdv the frame in place over the type-well and that the lug15 will prevent a lateral movement of the frame along the shift-rail. The frame is thus secured in position centrally of the type-well and in a position where any of the types on the various type -bars may be brought into contact with the face of the brush, as indicated in Figs. 1 and 2, by depressing' the key. The turning of the crank-handle at this time will cause the brush to be rotated, and an incidental longitudinal movement of the shaft will be effected, so as to give an axial movement to the brush, as well as to rotate it, thereby thoroughly cleansing the type-faces by the vrt/,ice

4movement of the brush across the type-faces in various directions. The bach andforth longitudinal movement of the shaft in its bearings is limited by the heads of the screws 28, which are adapted to bear against the inner faces of the side supports 21 of the frame. rlhe cleaning device may be readily removed by pressing the front end of the frame upwardly and rearwardly until the grooved portion 19 thereof is disengaged from the shiftrail' and block 15. A linger-piece 36 may be provided in order to facilitate the positioning of the device or disengagement of it from the type-writing machine.

From the foregoing description it will be seen that a simple, cheap, and efficient typecleaning brush is provided and one which may be readily attached to or detached from the type-writing machine to aord an individual cleaning of the type or types carried by each type-bar and that anatural oscillation or axial movement of the brush is effected while it is being rotated bythe crank-handle, so that the brush will move across the type-faces in various directions and a thorough and ecient cleansing of the type may be accomplished.
